One to whom money is owed (8)
I believe the answer is:
creditor
'one to whom money is owed' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for creditor that I've seen before include "Cried rot (anag.)" , "The one to whom debt is due" , "Director (anag)" , "to whom something is due" , "One who's owed money" .)
